504166 divided by 1 
The aim is to understand the frequency of 1 in 504166.

Let's proceed to step 1:
If we divide 5 by 1, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 0 after subtracting 5 from 5.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

Moving on to step 2:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 50.0
Subtracting 0 from 0 leaves us with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

Moving on to step 3:
1 goes into 4 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 504.0
Subtract 4 from 4 to get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

Step 4:
The number 1 fits into 1 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 5041.0
Deduct 1 from 1 and we're left with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 1

Step 5:
1 can be fit into 6 6 times, resulting in a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 50416.0
The remainder is 0 after subtracting 6 from 6.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 1

Let's proceed to step 6:
When dividing 6 by 1, we get 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 504166.0
Deduct 6 from 6 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
When dividing 0 by 1, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 504166.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
When dividing 0 by 1, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 504166.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 504166.0 with a remaining 0.0.
